The G2S is made with the same tool steel as the SSA and the sears are also wire edm'ed.
The main differences with the SSA are a different way of holding the hammer pin in, different pins, no laser marking and only spot MP check. Visually, from the outside of the gun there is no difference from the SSA and the feel and reliability is the same
